Rat lung inflammatory responses after in vivo and in vitro exposure to various stone particles

..The pertussis epidemic in Norway 1997-98 demonstrated decreasing vaccine immunity from age 5-6 years. The possibility of improving immunity against both diseases by a booster dose during early school age is therefore under consideration...

..The results indicate that a persistent ERK activation of a critical size leads to type 2 cell proliferation, and that the proliferative response may also depend on a MEK-independent ERK activation...

Active sick leave for patients with back pain: all the players onside, but still no action

Regression analysis with multiplicative and time-varying additive regression coefficients with examples from breast and colon cancer

Per Henrik ZahlSection of Medical Statistics, University of Oslo, NorwayStat Med 22:1113-27. 2003

Brominated flame retardants in archived serum samples from Norway: a study on temporal trends and the role of age

..The present study indicates an ongoing increase in human exposure to BFRs, and the current body burden appears to be independent of age, except for infants (0-4 years old), who seem to experience elevated exposure...

..No such links could be established. We therefore concluded that in these diazotrophic Synechocystis-type cyanobacteria the green light-induced transcription of the cpe operon directly required a functional apc operon...

Significance of Candida recovered from intraoperative specimens in patients with intra-abdominal perforations

..To assess the associations between birth weight or gestational age and risk of type 1 diabetes...

A variation of the amplified-fragment length polymorphism (AFLP) technique using three restriction endonucleases, and assessment of the enzyme combination BglII-MfeI for AFLP analysis of Salmonella enterica subsp. enterica isolates

B A LindstedtDepartment of Bacteriology, National Institute of Public Health, Oslo, NorwayFEMS Microbiol Lett 189:19-24. 2000

..The three-enzyme combination gave a higher discrimination, and is thus a new alternate way of performing AFLP fingerprinting of S. typhimurium...

Symptoms of anxiety and depression among mothers of pre-school children: effect of chronic strain related to children and child care-taking

..It is also important that selective fungal media be used in clinical studies of yeast infections...

The drinking water chlorination by-products 3,4-dichloro-5-hydroxy-2[5H]-furanone(mucochloric acid) and 3-chloro-4-(dichloromethyl)-5-hydroxy-2[5H]-furanone do not induce preneoplastic or neoplastic intestinal lesions in F344 rats, balb/ca mice or C57bl/6

..Based on an overall evaluation of these experiments, the intestinal tract, at least in rats and mice, seems not to be a main target organ for effects of MCA or MX on preneoplastic or neoplastic development...

Identification and characterization of quaternary ammonium compound resistant staphylococci from the food industry

..Cyanogen bromide cleavage of P1.19,15 PorA, peptide mapping, and sequencing of porA regions demonstrated that 2-1-P1.15 was specific for subtype P1.19, and henceforth it is to be redesignated as 2-1-P1.19...

R MehlLaboratory for Entomology, National Institute of Public Health, Oslo, NorwayAllergy 53:28-35. 1998

..01). Based on the assumption that the formation of ACF with high multiplicity is predicative for the tumour development we conclude that neonatal rats are more susceptible to PhIP and azoxymethane than adult rats...

The fungal cell wall component beta-1,3-glucan has an adjuvant effect on the allergic response to ovalbumin in mice

..A similar increase was not found for IgG2a. Our results show that beta-1,3-D-glucan provides a clear Th2-dependent (allergic) immune response to OA, indicated by elevated levels of IgE and IgG1 and not IgG2a, in the mouse model used...

..major protects against pneumococcal infection in mice when administered systemically prechallenge, and secondly that the protective effect is owing to stimulation of the innate and not the adaptive immune system...
